GPS Requirements
Overland Navigator expects that you have a GPS connected to your computer. While it will run
without a GPS, having one connected enables a variety of features. You will be able to automatically
position the map at your current location, record a waypoint, record a track, see the
latitude/longitude/altitude of the GPS, and see your current location/heading on the map. This
makes using a map easy and intuitive.
Before these features will be available you need to connect a GPS to your computer. The GPS you
select needs only minimal features, but must communicate with the computer using the NMEA0183
protocol. As Overland Navigator has maps and other features built in the GPS doesn’t require
them. There are numerous GPS devices available that simply determine your position and transmit
that position to the computer via USB, Bluetooth, or a serial cable using the NMEA0183 protocol.
These simple GPS models are often called a “GPS Mouse”, or “GPS Puck”. If you don’t know what
these terms mean, don’t worry; simply go into any electronics store show them this section of the
manual, and they will be able to help you out. The requirements are bare bones features that come
with nearly every GPS.
Once you have a GPS you will need to install it following the manufacturer’s instructions, and verify
that it is configured to communicate NMEA0183 on a physical or virtual COM port before
proceeding with the installation of Overland Navigator.
Map Installation
Overland Navigator Maps are installed separately from the Overland Navigator application. This makes
it possible to upgrade the application independent of the maps, install only those maps that you need,
and to add additional maps as your travels require.
These instructions are for the Utah Overland Navigator USGS Topographic Basemaps but the
instructions are identical for all other states/regions. Simply substitute your state/regions abbreviation
for “UT” in the dialogs below.
1. Locate Disk 1 of the map-pack to install; for example, “TOPO_UT_DISK1”.
2. Insert the disk into your PCs DVD Drive.
Note: If auto run is disabled on your PC, open Windows Explorer and double click the DVD icon,
and then double click on Setup.msi.
3. The Software Installer will run.
4. Follow the on-screen instructions as shown in the following steps.
5. Welcome Screen – Press Next
6. End User License Agreement – Read the entire license agreement. If you agree, check the box
next to “I accept the terms in the License Agreement”, and press “Next”.
7. Destination Folder – Select a suitable destination folder and Press “Next”.
If this is the first map-pack you’ve installed either install to the default directory shown, or press
the “Browse” button and select the folder where you wish to have the maps installed. If you
have purchased multiple map-packs, subsequent map-packs will be installed to the same
destination. Be sure that you have enough disk space for all maps you wish to install before
proceeding. For example, if you are installing Utah then Nevada you will be given a choice
during the installation of Utah and Nevada will be installed to the same location.
8. Confirmation – If you are ready to install, press, “Install”.
9. User Account Control – You may be prompted for permission to run the “Overland Navigator
Installer”. Press Continue to grant permission and continue with the installation.
10. Setup Progress – A dialog showing the progress will be displayed. Maps are quite large, and
installing them can take up to 45 minutes on slower DVD drives.
11. Installation Complete – When the maps have been installed a dialog will be displayed.
12. If you have other map-packs, repeat from Step 1.
Software Installation
This section describes how to install the Overland Navigator Software. See the previous section for
instructions on installing maps.

The Settings Utility will start and you will be presented with a window. The Setting Name is in the left
column and the Setting Value is in the right column. If you click on a Setting Name, a description is
presented at the bottom of the window. In this example, the Port Setting has been clicked, and its
description is presented at the bottom.
At a minimum, it is recommended that you configure the GPS Interface “Port” and the “Baud” Settings.
See Appendix A: Settings for a complete description of the various settings available.
2. When satisfied with your settings, press OK to Exit.
Usage
Getting Started
Starting the Application
Launch the application via “Overland Navigator 2.0.1 Settings” shortcut that is installed to the Desktop
and Start Menu.
Overland Navigator 2.0.1
By default, Overland Navigator will start in a window. If you prefer to run Overland Navigator in fullscreen mode you can adjust this via the “Run Fullscreen” option in the Settings Utility.
Overview
Assuming a GPS is properly configured Overland Navigator will startup similar to the screen below. If
the toolbars disappear, simply click or touch the screen someplace and they will re-appear. The toolbars
automatically hide when in “GPS” mode to display as much of the map as possible.
The toolbar along the left side of the screen controls the Overland Navigator Mode. The toolbar on the
top-right allows you to change the map scale, and the toolbar on the bottom right allows you to map
(record) the route you are traveling and mark points of interest. Your current position is shown on the
map as an X or a triangle with the lat/lon, elevation, and sunrise/sunset being displayed at the bottom of
the screen in the Status Bar. Some of the information will be missing or different based on your zoom
level, settings, and GPS status. Each of these features will be discussed in detail in the following
sections.
Mode Toolbar
Exiting the Application
To exit the application at any time, press the power button. If you are recording your GPS
track it will be written to disk, and all of your current settings will be saved. For example, if you are
recording a track on exit, Overland Navigator will resume track recording when the application restarts.
The Mode, last known position, zoom level, etc will also be recorded.
Panning
Select “Pan Mode” to specify where the map is centered using a mouse, pen, or
finger. To center the map at a specific location simply “click” or “touch” that location on the map.
Alternately you can “click and drag” the map to pan an entire screen at a time.
The GPS will remain active, and your position will continue to be displayed as you pan the map, zoom
in/out, and otherwise explore the map. You will know the mode is selected when its’ button is
highlighted.
GPS
Select “GPS Mode” to have the map automatically centered at the location of the
GPS receiver attached to your computer. The map will automatically re-center anytime the GPS position
gets close to the edge of the map. While in “GPS Mode” you can pan, zoom-in/out, etc except that the
map will automatically be re-centered after 10 seconds with no map interaction.
If the GPS isn’t connected for some reason, pressing this button will cause Overland Navigator to
attempt to connect. If the GPS connection fails, a message will be displayed letting you know.
Map Zoom
The map scale can be zoomed in or out via the Map Level toolbar. The “+” causes the map
to be zoomed in, and the “-” causes the map to be zoomed out. The maps will
automatically switch to the maps most appropriate for the current scale. For example, a
typical user with a USGS Topographic State Map Pack installed and the True Marble Satellite
imagery installed will see the maps change through 1:24k, 1:100k, and 1:250k USGS
Topographic maps and then change to the True Marble Satellite imagery as they zoom further and
further out.
Status
GPS receiver accuracy, location, altitude, and fix quality information are all presented via
the user interface. If the GPS is physically connected but the position and/or heading are
unknown a red X will be shown. The red X can also be shown if satellite reception is
temporarily lost.
When the position and heading are accurately known, a triangle will be displayed at the
current GPS position. The triangle will point in the direction the GPS indicates it is traveling.
The location, altitude, and sunrise/sunset times are displayed in the status bar at the bottom of the
screen. The location and altitude are displayed exactly as they are reported by the GPS. The format of
the location is selectable between various lat/lon formats, UTM, or both UTM and Lat/Lon.
The sunrise/sunset time is calculated for your current GPS location. The displayed times reflect the
timezone offset and daylight savings offset in observation at your current GPS location.
The accuracy of these values is dependent upon the specific GPS receiver being used and on the current
state of the GPS satellite network. Elevation in particular is often very inaccurate. Be sure to research
the accuracy of your GPS to insure that it is suitable for your application. Note that maps also have
multiple sources of error that when compounded with GPS error can yield very unreliable information.
You should always verify your position using current paper maps and charts.
In addition to elevation error, GPS Elevation and Map contour elevation are measured against different
vertical datums. A vertical datum is the approximate ellipsoidal shape used to model the earth when
mapping it. USGS Maps and the GPS measure elevations against different vertical datums. You cannot
compare GPS Elevation with the elevation reported on a USGS Topographic map and expect them to be
the same.
Recording Waypoints
The “Record Waypoint” button allows you to mark your current GPS location with a symbol.
This is a useful way to mark a point of interest (POI). For example, if you are traveling
around and notice an interesting hiking trail you can record a “Hiker” symbol. Later, when
you return to the area you’ll be able to quickly find your way back to the trail.
The “Record Waypoint” button will only be displayed if there is a GPS connected to Overland Navigator.
The waypoint is recorded to the daily GPX track in your “Track Directory” (See Appendix A: Settings).
The daily track is named by the date. For example, if today is January 12, 2009 then the GPX file will be
named 20090112.gpx. You can share the GPX files with others and they can view them and download
them to their own GPS units to retrace your steps.
To use the feature press the “Record Waypoint” button and a symbol chooser dialog will appear. Select
the symbol you wish to mark your location with, and press “OK”. If you change your mind and don’t
want to record a symbol, press “Cancel”.
Recording Tracks – AKA breadcrumb trail
The “Record Track” button allows you to record the path that the GPS is
traveling. Press Record to begin recording the track and the button will change to a “Pause” button that
is active (blue highlight). Press the “Pause” button to stop recording the track. The track that is
currently being recorded will be displayed as a red line.
The “Record Track” button will only be displayed if there is a GPS connected to Overland Navigator. The
track is recorded to the daily GPX track in your “Track Directory” (See Appendix A: GPS Tracks). The
daily track is named by the date. For example, if today is January 12, 2009 then the GPX file will be
named 20090112.gpx. You can email these track to your friends and they can view them in popular free
software, with online viewers, or download them to their own GPS units to retrace your steps.
Displaying GPS Tracks
Overland Navigator can display the contents of multiple GPS eXchange (GPX) files at the same time.
These file can be located in your “Track Directory” or removable media devices such as USB thumb
drives, memory sticks, and CDROMs. GPX files can be from any source including, but not limited to,
those recorded with Overland Navigator, recorded with another GPS, created with a mouse in desktop
mapping software, obtained from a friend, or downloaded from the Internet.
There are two ways you can display a GPS track by placing it in your track directory or by inserting
removable media that contains tracks.
To display a GPX file in your track directory:
Copy the GPX file to the configured “Track Directory” (See Appendix A: GPS Tracks). If Overland
Navigator is running, the track will be displayed immediately. If Overland Navigator isn’t
running, start it and the GPX file contents will be displayed. If the file already exists, but the
copied file is newer, Overland Navigator will display the updated file. Note: You do not need to
stop Overland Navigator to perform this operation.
To display a track that is stored on removable media:
1.
Copy the GPX file(s) to the root directory of removable media such as a USB Thumb Drive,
CDROM, or memory stick. The root directory means that the file isn’t inside of a sub-folder. For
example, if your thumb-drive is located at “F:\” then all GPX files must be located in “F:\” and
not “F:\gpx” or some other sub-directory.
2. Verify that Overland Navigator is running. If it isn’t, start Overland Navigator before proceeding.
3. Insert the removable media device.
4. All of the GPX files on the device will be displayed on the map.
Advanced Operation
Automated Position Reporting System (APRS)
APRS is an amateur radio based Automatic Position Reporting System for tracking and digital
communications. APRS and amateur radio are frequently used in Search and Rescue (SAR), Research
Expeditions, Vehicle Dependent Expeditions, Offroad Clubs, and Mountaineering Expeditions to keep
track of people, vehicles, and other resources. While enthusiasts will note that APRS is much more, at
the simplest level APRS allows users to share their current location, or the location of *something* via
amateur radio so that other users can view it on a map/GPS. Here is a snapshot showing a Kenwood
radio user, home user, pickup, a weather station, a repeater, and an Internet Radio Linking Project (IRLP)
node. All of the symbols used by Overland Navigator are shown in Appendix C: APRS Symbols
Overland Navigator supports APRS capable devices in several ways:
1.
Overland Navigator has a bi-directional NMEA Interface that both outputs NMEA to your APRS
device and listens for NMEA sentences as input . When you think about Overland Navigator,
think of it as if it *is* a GPS. Just as many handheld GPS units support bi-directional NMEA0183
communication, so does Overland Navigator. When you configure the NMEA Interface in the
settings application NMEA is streamed to the connected hardware. Supported NMEA
sentences heard from the input GPS will be passed on to the NMEA Interface where your APRS
device is attached.
NMEA
GPS Puck
NMEA
Computer
Radio/TNC
$GPWPL or $PKWDWPL
2. Overland Navigator can display stations that are heard by your APRS device if it outputs the
$GPWPL or $PKWDWPL NMEA0183 sentence types. They are displayed as waypoints. Because
they are heard live over the radio, we refer to these as “Live Waypoints” throughout the
documentation and settings program. This is in contrast to a fixed waypoint that you might
have in a GPX file.
Many popular APRS devices, such as the Kenwood D7/D700/D710 radios, the Byonics
TinyTracker 4, the Argent Data Systems Tracker2, and the Argent Data Systems OpenTracker+
support $GPWPL and/or $PKWDWPL sentences. Other devices do as well.
3. In contrast to most GPS units, when new stations are heard, Overland Navigator will update the
location on the map instead of adding a new waypoint. This greatly reduces the amount of onscreen clutter and removes the need to manually delete waypoints.
4. These “Live Waypoints” automatically fade away and then expire on their own. This allows you
to quickly see which stations haven’t sent a recent position report, and removes stale positions
from the map. Below, the SEDRO repeater is just about ready to fade away completely and be
removed.
5. Overland Navigator has complete support for APRS symbols, including the most recent overlay
symbols. The symbols were designed from scratch to be consistent, high contrast, easy to read,
and easy to distinguish from non-APRS waypoints (round vs square).
Instructions for setting up Overland Navigator with a Kenwood D710, Argent Tracker2 Model T2-301, or
an Argent OpenTracker+ are available in Appendix D: APRS Setup. As users configure additional
devices, we’ll try and include the instructions on our website.
To setup APRS on another device:

Purchase a radio or tracker that can output heard stations to a GPS; preferably one that supports
the $PKWDWPL sentence type. $GPWPL will also work, but all stations will use the same icon.

Connect a cable from the Overland Navigator PC to the GPS input connection of the APRS device.
You’ll know you have it right when your APRS device indicates that it has good GPS input.
Assuming a DB9 serial connector for the PC side, wire the cable up to a connector that matches the
GPS port of your APRS device. Use the following as a guide:
PC (9 pin D-SUB terminal)
GPS
DB-9 pin 5
GND
DB-9 pin 3
Rx (Receive)
DB-9 pin 2
Tx (Transmit)

Configure the Overland Navigator NMEA Interface port and baud rate settings to match your APRS
device settings.

Configure the Live Waypoint Expiration setting to something you find reasonable. This value
controls how long an APRS waypoint will be displayed before being removed from the map. It will
fade throughout its lifetime.

Configure your APRS device following the manufacturer settings.
Keyboard Control Input
Most Overland Navigator functionality can be controlled via the keyboard. The keys used to execute an
Overland Navigator action are configurable via the Settings application. See Appendix A:
Keyboard Control for a list of the default key/function settings and instructions on how to create your
own custom key mappings.
Remote Control Input – Windows Messaging API
Overland Navigator supports automation via a Windows Messaging API. Using programs such as Girder
(http://www.promixis.com/) nearly all of Overland Navigators functionality can be controlled from other
software or a wireless remote control. This enables Overland Navigator to be seamlessly integrated
with other software and makes it ideal for map presentations such as expedition briefings and trip
reports.
Overland Navigator exposes the following commands via the Windows™ WM_COMMAND message.
Configure your remote control software to send a WM_COMMAND to the OverNav window class.
Specify the wParam value from the table below that corresponds to the function to be executed. Some
commands can make use of an optional argument specified by lParam.

Many GPS units are connected via
Bluetooh or a USB cable and create
“Virtual” COM ports. These Virtual COM
ports are not created until the GPS is
plugged in. The Settings utility can only
list COM ports that are created. You
will need to have your GPS plugged in
before performing the configuration.
Note: Many SIRF III GPS receivers are capable of speaking either SIRF III Binary or NMEA0183. Please
consult your GPS User Manual if you need to set your GPS to output NMEA0183.
Baud – Speed at which GPS communicates
Options: 110, 300, 600, 1200, 2400, 4800, 9600, 14400, 19200, 38400, 56000, 57600, 115200, 128000,
256000 (Default: 4800)
NMEA0183 Supported Sentences
The following sentences are supported by Overland Navigator on both the GPS and NMEA Interface.
$GPRMC - Position, Speed, Course – REQUIRED
$GPGGA - Altitude, Quality, HDOP – REQUIRED
$GPGSA - Fix, Fix Dimensions (2d or 3D), HDOP
$PGRME - Garmin Error - An accurate error circle will be displayed if this sentence is observed.
$GPWPL - Waypoints heard on either the GPS Interface or NMEA Interface will be displayed.
$PKWDWPL - Kenwood Radio Waypoints. Waypoints heard on either the GPS Interface or NMEA
Interface will be displayed.
$GPGLL – Not used, but passed through to output port when configured.
$GPVTG – Not used, but passed through to output port when configured.
$GPGSV – Not used, but passed through to output port when configured.
NMEA Interface
The NMEA Interface settings allow you to configure a COM port for bi-directional NMEA communication.
This allows Overland Navigator to behave like any handheld GPS and exchange NMEA input/output with
other NMEA compliant devices (E.g. An APRS tracker). See GPS Interface for a list of the supported
NMEA0183 Sentences. Overland Navigator will send the GPS Input it receives out to this port and listen
for $GPWPL and $PKWDWPL sentences that tell it to put a waypoint on the map dynamically.
The settings specify where and what speed the data should be output. Be sure to load any drivers and

Appendix B: Troubleshooting
Unable to connect to GPS
If the GPS is configured improperly, has become physically disconnected, or isn’t ready to communicate
with an application you may receive an error message, “Unable to Connect to GPS”. To fix this you will
need to determine what the underlying cause is, and then correct it.
Verify the connection

If the GPS connects via a cable, verify that the GPS is physically connected to the computer.

If the GPS connects via Bluetooth, use your Bluetooth administration tools to verify that the GPS
wireless connection has been made. Vehicles in particular have all sorts of electronic noise that
can interfere with Bluetooth. You may need to reposition the GPS or computer so the
connection can be made.
Verify the COM port

Go to the Control Panel

If you are running Vista, switch to Classic View (left hand margin)

Run Device Manager

Click on the Plus sign next to “Ports”

Verify that your GPS is displayed as a COM port. If it is missing, refer to your GPS and/or
Bluetooth manuals for the steps necessary to configure your GPS.
Verify Overland Navigator Settings

If you are sure that you have the correct COM port configured, be sure to verify that the baud
rate is correct.
Refer to the Installation Section and Appendices for information on configuring Overland
Navigator GPS Settings.

Test with Overland Navigator again. If Overland Navigator is already running, press the “GPS”
button and Overland Navigator will attempt to connect using the current settings.
Verify that Overland Navigator has exclusive GPS access
Only one application at a time can access the GPS.

Verify that the GPS Settings or monitoring utility that came with your GPS is not running.

Verify that other mapping applications aren’t running

Verify that Overland Navigator isn’t running twice. Especially when running full-screen it can
sometimes be difficult to realize that it was started twice.
Verify the GPS is in NMEA0183 Mode
Many GPS manufacturers support both a proprietary “binary” mode and the open/standard NMEA0183
mode. Refer to your GPS manual for instructions on setting the output mode to use the NMEA0183
protocol.
Create a log file of the GPS/NMEA data
To capture a log file, press ctrl-alt-l (lowercase L). Press it again to stop collecting. The logfiles will be in
your Track Directory and will end in “nmea”.
These are human readable files that you can inspect to determine if your devices are outputting proper
NMEA0183 sentences. Please see the list of supported NMEA sentence types in Appendix A: GPS
Interface
Vista and Delorme PN-20 GPS
To use a DeLorme Tripmate GPS with Vista 32 you will need to disable Vista’s User Access Control (UAC).
If you are using a DeLorme Tripmate GPS under Vista 64 it will not work with Overland Navigator. If you
are using Vista 32 it will work only if you disable Vista User Access Control (UAC). DeLorme includes a
proprietary program that interfaces with the Tripmate GPS and creates a Virtual COM port. Vista’s UAC
restricts non-DeLorme software from interfacing with it.
Garmin 60CSx / 76CSx
The Garmin 60CSx has both a mini USB port and a 4 pin serial port on the back of the unit. The USB
port does not support NMEA0183. In order to use the 60CSx you will need to connect via the 4 pin serial
port or use software to convert the USB port output to NMEA0183.
Note: There are several USB GPS units available for about $35 that have the same chipset internally as
the Garmin 60CSx. For example, the GlobalSat BU-353 magnetic mount GPS is in use by many of our
customers.
Connecting Via the Four Pin Serial Port
To configure a Garmin 60CSx for NMEA output you will need a Garmin PC Interface Cable.
If your computer doesn't have a serial port, you may need to use a Serial to USB adapter
Once you have the GPS connected to the computer with a new COM port showing in Device Manager,
follow these steps to configure the 60CSx to output NMEA.

Turn on the GPS
Press Page until you get to the "Main Menu"
Select "Setup" and press Enter
Select "Interface" and press Enter
Select NMEA In/NMEA Out in the "Serial Data Format" field.
Press the Quit button
You can now use the Overland Navigator Settings utility on the computer to select which COM port the
GPS is connected to.
Connecting via the Micro USB Port
The micro-usb port on the 60CSx communicates via the proprietary Garmin Binary protocol. Overland
Navigator communicates via the industry standard NMEA0183 protocol. There are two potential
options for getting the GPS to appear as an NMEA0183 compliant device to Overland Navigator:
1. There have been some reports of users installing the Garmin Spanner Software which converts from
the Garmin Binary Protocol to NMEA0183. This has not been tested. The Garmin Spanner software is
available as a free download from Garmin.
http://www8.garmin.com/support/download_details.jsp?id=1627
2. Fransson GPSGate is a program that supports many GPS protocols, allows you to share the GPS
amongst multiple applications, and much more. It can be configured to listen to the Garmin GPS and to
convert from Garmin binary protocol to NMEA0183 that is output onto a "Virtual COM port". Overland
Navigator can be configured to listen to the Virtual COM port that Fransson GPSGate creates. GPSGate
has a free 30 day trial.
Blank/Black Screen
This usually happens when your GPS has positioned you someplace where you don’t have maps. If you
have the Satellite Imagery installed, you can zoom out until the imagery appears, then zoom back in to
the location where you have topographic map coverage.
Overland Navigator will never allow you to pan beyond -180/180 degrees longitude, or -90/90 degrees
latitude.

The following configuration guides are provided for information purposes. While all of the devices have
been verified to work, usually by the manufacturer, we don’t have hands-on experience with all of the
equipment and cannot offer complete support for them. You will need to work with the manufacturer
to resolve any hardware specific issues. We are of course happy to resolve any Overland Navigator
specific configuration issues and help you gather a log files with the data being streamed across each
interface (GPS Interface, NMEA Output, NMEA Input). Armed with the log file, we can help identify what
the problem might be, which will help you when interacting with your equipment manufacturer.

Argent Data Systems - Tracker2 Model T2-301
The Tracker2 model T2-301 from Argent Data Systems is a 5 Watt radio transceiver with a Tracker2 unit
built into the radio housing. The Tracker2 functions as a terminal node controller (TNC) fully optimized
for APRS functions and applications.
The Tracker2 model T2-301 will provide APRS position data output in the form of waypoints. The
waypoints can be provided in several selectable NMEA formats. When the T2-301 is connected to
Overland Navigator 2.0.1, those positions will be plotted on the moving map displayed as Live
Waypoints (refer to the User Guide description of Automated Position Reporting System (APRS)
features). The Live Waypoints may be displayed in the form of simple bubble icons or as APRS symbols if
the Tracker2 T2-301 is instructed to use the $PKWDWPL NMEA format.
To connect the Tracker2 T2-301 to Overland Navigator, use the following general steps:

Configure the Tracker2 T2-301 for APRS operations using the T2-301 Serial + Power Cable and a
power source as described on the Argent Data System website. For use with Overland Navigator
2.0.1, only the T2-301 Serial + Power cable is required. In this configuration, Overland Navigator
2.0.1’s ability to pass GPS NMEA data to the tracker eliminates the need to have a separate GPS
unit dedicated to the tracker.

Connect the Tracker2 T2-301 to your computer using a null modem serial cable. If you do not
have a serial connection on your computer, a USB to Serial converter cable will be required. A
driver may need to be installed prior to using the converter cable.
Note: A null modem cable resembles other serial cables, but the internal wiring is modified to
work with data devices. A null modem cable is often marked on the connector to indicate its
unique configuration. Null modem adapters are also available to convert a serial cable to a null
modem serial cable.

Use the otwincfg.exe configuration utility provided by Argent Data Systems to configure the
firmware in the Tracker2 T2-301 for APRS operations as explained in the Tracker2 User’s
Manual. A callsign must be added, but the default settings for other parameters support typical
APRS operations. Tactical callsigns such as “Leader” or “Chase1” may be used, but your amateur
radio callsign must then be included in the comment block in order to meet FCC regulations for
station identification. In the utility, verify that Serial Port A is set to “4800” and “Auto”.
Note: In addition to the otwincfg.exe utility, the Tracker2 may be configured using a terminal
emulation program such as HyperTerminal or PuTTY. A terminal emulation program will be
needed to configure the Tracker2 T2-301 output waypoints in the $PKWDWPL format necessary
to display APRS symbols for Live Waypoints created by Overland Navigator. The format for this
command when using the terminal emulator is “PROPWPT ON”. Further information is available
in the Tracker2 User’s Manual.

Close the otwincfg.exe utility and any other program using the COM Port connected to the
Tracker2 T2-301.

Open the Overland Navigator settings utility. Under the “GPS Interface” item, enter the COM
Port that is connected to the GPS unit providing position information to Overland Navigator
(refer to GPS Interface in Appendix A: Settings). Select 4800 for the baud rate.

In the Overland Navigator settings utility, expand the “NMEA Interface (Optional) item. Select
the COM Port connected to the null modem cable from the Tracker2 T2-301. Select 4800 as the
baud rate.
Note: Due to the nature of the ‘virtual’ COM Ports created by USB to Serial converters, the COM
port may not exist until the converter is connected. Make sure that the GPS and the converter
cable are connected to your computer before attempting to configure Overland Navigator.
Overland Navigator is now ready to use with the Tracker2 model T2-301. Vehicles or stations
broadcasting APRS information will be displayed on your map screen along with their ID.
Argent Data Systems - OpenTracker+
The OpenTracker+ from Argent Data Systems will receive APRS data from your existing mobile radio and
output position data in the form of waypoints. When the OpenTracker+ is connected to Overland
Navigator 2.0.1, those positions will be plotted on your moving map display as Live Waypoints (refer to
User Guide description of Automated Position Reporting System (APRS)). Overland Navigator 2.0.1 is
capable of passing GPS data to the OpenTracker+, thereby eliminating the need for a second GPS unit
dedicated to APRS.
To connect the OpenTracker+ to your mobile radio and Overland Navigator, use the following general
steps:

Connect your radio to the connector marked “RADIO” on the OpenTracker+ using an
appropriate cable as described in the OpenTracker+ User’s Manual. The RADIO connector on
the OpenTracker+ is similar to that used on the Kantronics KPC-3 and the Byonics TinyTrack3.
Cables made to interface a radio to those units should also work with the OpenTracker+.

Connect your computer to the connector marked “DATA” using a ‘null modem’ serial cable. If
your computer does not have a serial port, connect the null modem cable to a USB to Serial
converter cable and insert the USB end into your computer. A driver may need to be installed in
your computer prior to using the converter cable. As noted in the OpenTracker+ User’s Guide,
the PC does not provide power to the tracker. See the OpenTracker User’s Guide for suggested
power sources.
Note: A null modem cable resembles other serial cables, but the internal wiring is modified to
work with data devices. A null modem cable is often marked on the connector to indicate its
unique configuration. Null modem adapters are also available to convert a serial cable to a null
modem serial cable.

Using the utility otwincfg.exe provided by Argent Data Systems, configure OpenTracker+ for
APRS operations as directed in the OpenTracker+ User’s Manual. No special settings are
required to use the OpenTracker+ with Overland Navigator.

Close the configuration program and any other programs using the COM Port connected to the
OpenTracker+.

Open the Overland Navigator setting utility. Under the “GPS Interface” item, enter the COM
Port that is connected to the GPS unit providing position information to Overland Navigator
(refer to GPS Interface in Appendix A: Settings). Select 4800 for the baud rate.

In the Overland Navigator setting utility, expand the “NMEA Interface (Optional) item. Select
the COM Port connected to the null modem cable from the OpenTracker+. Select 4800 as the
baud rate.
Note: Due to the nature of the ‘virtual’ COM Ports created by USB to Serial converters, the port
does not exist until the converter is connected. Make sure that the GPS cable and the cable
used to connect the OpenTracker+ to your computer are plugged in before attempting to
configure Overland Navigator.
Overland Navigator is now ready to use. Other vehicles or locations broadcasting APRS information will
be displayed on your map screen. Due to the type of NMEA data word provided by OpenTracker+, Live
Waypoints will not be displayed using APRS symbols. Live Waypoints will be shown as a round waypoint
marker labeled with the station’s ID.
